when only using lepton it did not matter if I used allowprogressive or not. the result was always 2.2MB file
When running with OptimalCompression=false on my test image, result was again 2.3MB and then lepton further reduced it to 1.9MB only after I enabled progressive.
Maybe my image is progressive I'm not sure
